Jamieson, Fausset & Brown, on 1Tim 6:4

“He is proud, knowing nothing, but sick about questions and strifes of words; from which arise envies, contentions, blasphemies, evil suspicions,”

“He is proud--literally, "wrapt in smoke"; filled with the fumes of self-conceit (Ti1 3:6) while "knowing nothing," namely, of the doctrine which is according to godliness (Ti1 6:3), though arrogating pre-eminent knowledge (Ti1 1:7). doting about--literally, "sick about"; the opposite of "wholesome" (Ti1 6:3). Truth is not the center about which his investigations move, but mere word-strifes. questions--of controversy. strifes of words--rather than about realities (Ti2 2:14). These stand with them instead of "godliness" and "wholesome words" (Ti1 6:3; Ti1 1:4; Tit 3:9). evil surmisings--as to those who are of a different party from themselves.”
